Application filed Jul 26 T 0 aZZec/ wm it may concern Be it known that I,.VTILLIA1I Jonxsrox FRAME, a subject of the King of Great "Britain, residing at Glasgow, Scotland, have invented certain new and useful Improvements in Hydraulic Apparatus for EX 'haustino; or Extracting Air,G-as,or Vapor,

In accordance with my invention of which the following is a' specification .TlllS invention relates to hydraulic apparatus for pumping or, exhausting air, gas,

or: vapor, antl'has for its object to improve the construction thereof and produce a de- Vice of increased elficiency.

a large volume of water, which-may beat low pres- ,sure,'is conducted to a a chamber provided. with means for. splitting or dividing the -water into a. series of sheets :or laminae.

. thereby converting the potential energy ofi hausted-or pumped is preferably drawn into the water intokinetic energy, these sheets being split upor sub-divided, cross-wise, by means of one or' more deflectors preferably arranged before or. within a. chamber which may have conic or otherwise converging walls. Qlhe an, gas, or" vapor bemg ex divided into sheets and the pointof its sub-1' division and deflection, the air gas or vapor being delivered between the sheets and entrainedby the water as the sheets are de *fiected and turned upon themselves. The

arrangement is such that cross currents'or streams of water are set up within th-econverging" chamber, and these crossstreains iinpingeQon the undeflected sheets of water,

thereby" driving.the air, gas or vapor,

drawn into the apparatus, into the mass of flowingwater and charging t with a large volume of air,'.gas or vapor whichis finely diffused or spread (more or less as bubbles), among the'water.

In, order that the invention may be clearly understood, I have hereunto appended an explanatory sheet of drawingswhich shows,

by way of illustration or example, one

method of constructing an apparatus in accordancewith the invention and for the purpose of exhausting or extracting air.

Figure 1 is avertical section of the apparatus. Fig.2 is a cross sect-ion of the same on the line A, A, Fig. 1.- Fig. 3 1s a plan of Specification of Letters Patent. 1

the plgite 2. Fig. 4 is a. cross section of the p ate A large volume of water is used, this water being drawn from a river, sea, orother convenient and available source of supply. The water is conducted to a chamber or. nozzle 1 which,"as will be seen, has preferably a converging internal wall. The arrow at a? shows the direction of the flow of thewater. The water is delivered from this chamber or nozzle to a grating shown in, the form of a plate 2 which is preferably of circular shape, as shown at Figs. 3 andfl, and is provided with a series of cross bars-3 which may be formed with deflecting surfaces at the water entering side. as shownjat 4. Between the bars of the plate are slots or passages-5 through which thewater passes in a series ofthin sheets or laminae, which latter impinge upon the upper tapered portion 7 of a deflecting cross bar 6 arranged in the chamber 8 which chamber, at its upper end, has one, two, or' more air inlet branches. 9shown as deliver- -ingair at points beneath the-ends of the bars 3. Below the bars is a chamber preferably with downwardly and inwardly inclined deflectors or walls shown at 10- as conic in form and having a throat 11, below which is a diverging passage 12 and a discharge or outflow pipe 13. The cross bar 6 may be tapered toward its lower side 14, if so desired, as Well as its upper side.

The chamber 1 is provided witha flange 1'5 for;coupling it to the inlet pipe and with a flange 16 for. securing it to the flange (shownmlotted) of the chamber 8. The plate 2 is secured in place between the chambers' 1 and 8, as shown, and the plate may be provided with two or more holes into which fit'upw'a-rdly projecting studs 18 at the top of the chamber 8, thereby preventing the plate turning around, as it is desirable'that the slots or'passages5 be at right angles to the cross bar 6;

The branches 9 are each provided with a flange 17 for coupling the same to the suction pipes. I

The apparatus may be made of any convenient size to suit the vacuum andvolunne of air required to be extracted, and. its parts may be modified. or altered to suit local conditions. It may be-provided Withtwo or more cross'deflecting bars 6 if so. desired;

. With this apparatus the large volume of water entering at a 'is split up into a series ofthin sheets or laminae on passing through the slots 5. These thin sheets or laminae are cut cross-wise .and divided by means of the bar 6 being atthe same time deflected to either side of said bar 6 into the converging passageways b and 0 ateither side of said bar. in through the air inlets '9, 9, and carried down between the'sheets. The action of the bar tlcombined with that of the converg ing walls of the cone 10 is to fold back the edges of the sheets upon themselves and to. cause part of the water to flow in cross currents or streams-which impinge on the undefiected sheets of water, thereby infolding and impounding the air drawn into the apparatus,,and driving it into the mass of water and charging the same with a large volume of air-which is .finely difiused or spread (more or less as bubbles) among the water. The water, thoroughly aerated or' charged with air in this manner passes through the throat 11' and then its velocity is reduced in the diverging chamber 12.
